Temporary workaround for plug-in chips on the lockscreen

This change disables the chip animation for the lock screen statusbar when the user has two different wallpapers on the lockscreen and homescreen due to the reasons described in b/275209644. This CL can be reverted as soon as the LOCKSCREEN_LIVE_WALLPAPER flag reaches droidfood.

Bug: 275209644
Test: Manual, i.e. testing plug-in chips on the lockscreen and homescreen with different wallpaper configurations (same wallpapers, different wallpapers, live wallpapers). Switching between lockscreen and homescreen during chip animations.
